A lot of Pale Ales, it looks like. All the pre-war beers in the table are Pale Ales. pretty low-gravity Pale Ales. All are under 1040º. I know I've warned you about this before, but it bears repeating: don't assume that those 60/- Ales have any connection with modern Scottish 60/-. These were all clearly indicated as Pale Ales. The colours also show that they weren't dark like today's 60/-.
1038º was pretty weak for a London Pale Ale before WW II. Especially a draught Pale Ale. Standard Bitter was in the mid 1040's and Best Bitter over 1050º. The only beers with a similar gravity to Deuchar's were cheap bottled Pale Ales like Barclay Perkins XLK or Whitbread's Family Ale, which were both in the 1036-1038º range.
See anything unusual about the post-WW II beers? With the exception of one Pale Ale from the dark days of 1949 austerity (when Britain was most definitely in black and white) all are over 1040º. Normally you would expect the earlier beers to be stronger. There's a reason for that. The 1950's Pale Ales are of a different type: Export. It does appear that in the 1950's it was beginning to take on its modern form. Though today's Exports are a little lower in gravity, in the range 1042-1045º.
The Hampden Red Ale is an odd one. My guess would be that it's the Export with extra caramel to give it a darker colour. I'm trying to think if I've seen another Scottish beer described as a Red Ale. I don't believe I have. But I'm sure that won't stop some style Nazi making up guidelines and a fake history for it.
Finally there are a couple of Scottish-style Sweet Stouts. I didn't need the hint in the name to see that they were Sweet Stouts. The low attenuation gives that away. Though they aren't the most extreme in that respect. Plenty of Scottish Stouts had below 50% apparent attenuation.
